Figure 2 1s an lenlarged viewl compared ywith Figure 1 showing the invention in sec,- tion onthe line `2 2 of Figure 1;

A Referring to the drawlngs' in detail by ref- Y f y erenoe numerals, 10 designatesa binder .hav` ving drive mechanism 11 thereon which constiv tutes a plurality of sprocket wheels and vroll- 'fV 40 ,ers and a sprocket chain 12 trained-th-ere about, the sprocket-wheels being driven Afrom a sourcekof power linl a'y well known manner. 1 13 designates vthe platform of the binder A j above which is positioned the platform can-Y *4&5l vas 14 in the form of alrendless belt having .fcleatsf rl5l thereon for i Carrying i the straw t 2thereover, the endless belt being `trained labout suitable rollers, one o fl which is shown fats-16 asmounted .on' a shaft17 -journaled in suitable bearings as at 18 and having la pro- Jecting portion 19 extending beyond one of y said bearings into a clutch casing 20fsecuredy V,tothetbinder.' The top '21 of the casing is suitably slotted as at 22 to permit ofthenecessary movements ofthe clutch lever 23 which '55Av isfpivotally mounted atjits lower end to the bottom of the casingas shown vat 24;,and abolt 25 securedfbetween two up'standin'gv ears 26. Loosely mounted upon the eXtensio`n 7`19 of vthe vshaft 17 is a sprocket wheel -6o 27 1n driven connection with the sprocket chain lllfand secured against'longitudinal f v,inovement. of the shaftextensi'on 19 by means of Va flangef28 secured to thehub 29 thereof,

said flange resting against one vWall of the n casing and being held in place by members SOfEsecured tosaid wall and having off-set fingers 30 adaptedz'to lie in radial relation to jsa'id flange andV against the surface there- 0f opposite to the above mentioned'wall asv 10 Y 'clearlyshown in Figure` 2. Slid'ably, but

Anon-.rotatablymounted uponr the yextension 19 is a A clutch collar 31 vhavingy a clutch inemberthere'on adapted to be brought into articulaterelation withv a similar clutch 75 member 33 on the hub." The collar 31 is provided with a longitudinalgroove having re- :lc'eived thereinA a longitudinally extending);

spline Blf-located onthemshaft extension 19A thereof, The collar 31-is provided with 'la radial extending flange 35 formed integrally y' therewith and a' removableycollar 36 thread` in spaced'rela'tion to each other and torevceive therebetween a ring 38 to Vwhich the yoke 39for1ned on the lever .o23 is pivotally sur`r connected by means of threaded lugs 40 se- I cured to said ring and having their outer ends riding in" elongated slots 41 formed in said yoke at diametrically opposite points. The ring '38 is loosely mounted on the collar 31 to afford a certain amount of play relative thereto in the operation of the lever. The colment.

lar is prevented from disengagement With the extension 19 by means ofV a ring member 42 threadedly connected therewith and being prevented from Vaccidental displacement by the set screvxT 48. Extending from the top of the casing are apertured bracket members 44 and 45, the apertures of said bracket members being in alignment With each other and having slidably mounted therein, a shouldered detent 46 having a' bullet shaped, and

rounded end at 47, having at its rear end a flange 4S, providing the' above mentioned shoulder. Between the shoulder and the bracket 44 is provided a helical spring 49,V

the ends of which abut respectively der and the bracket.-

r1`he operation of the clutch 4mechanism is as follows: When it is desired Vto place the the shoulapron 14 in'connection with the driving mechanism of the binder, the lever 23 is moved to the left (considering the mechanism as shown in Figure 3) and suoli niovementvvill force the head 47 out of its path in such move- The head 47 Will turn to its normal position as soon as the lever has past, preventing the same from turning'to thefull articulate relation to each other and Will start or stop the belt from rotation.

Advantages of' the provision of a clutch of this character in this connection is that the apron may be disconnected from the guidand clutch, and having a slot in the top thereof, a yoked lever pivotally mounted Within the casing andk having pivotal connectionV With said collar, said lever projecting through said slot, spaced iianges depending from the top of the casing adjacent said slot, and a detent yieldably and slidably mounted on said ianges to extend across the path of movement of said lever.

In testimony whereof I affix my signature.
